. My invention relates to improvements in tobacco pipes, and particularly tobacco pipes the bowl and the stem of which are detachably connected. An object of the invention is to provide a tobacco pipe having a stem which will be firmly engaged and yet easily separable from the bowl thereof; even when the parts are in moist or soggy and expanded condition; to enable the pipe to be cleaned and for other purposes.

A pipe of this character will meet the needs of smokers who find it very difficult to take ordinary pipes apart. For instance, a pipe which has a stem suitably fitting the bowl while being smoked, will, if laid aside for a time to dry, soon attain a state in which the stem sticks fast to the bowl and cannot be removed until the pipe is again smoked and allowed to moisten. *When dry, the stem and bowl adhere together very firmly, but when moist, the stem can be taken out. The moistening of the parts may result in a small increase in the diameter of the hole in the bowl to receive the stem. This increase, as the stem and bowl no longer stick fast, facilitates the separation thereof.

Another object of the invention is to provide a tobacco pipe of such construction that one of the chief members thereof, such as the stem or the bowl, will be held in place by a clamping effect sufficient to join the principal parts of the pipe securely together, while at the same time the stem can be readily withdrawn from the bowl when the smoker desires. In one case the stem of the pipe may be adapted to give somewhat, and in another form the bowl may be designed to have such an action; or if preferred, both the bowl and the stem can be made to cooperate in this way. In other embodiments, an additional element may be provided to engage the bowl on the one hand and the stem on the other in a manner to maintain the firm engagement of these parts, but always in condition to enable the pipe and stem to be disconnected.

A further object of the invention is to provide a tobacco pipe of such construction that the opening to receive the stem is of large size, and the communication from this hole to the tobacco chamber is likewise of large size, so as to facilitate cleaning and airing when the pipe is disassembled. With the variation of the wood between dry and soggy condition, the moderate change in dimensions requires extra care for the sealing between stem and bowl. To this end, resilient means are provided to hold the stem and the bowl in continuously sealed relation.

An additional object is to impart to a bowl having large openings and passages a resilience which holds the stem in the opening at the bottom of the tobacco chamber in sealed relation, in spite of the variation of the wood.

With these and other objects and advantages in view, as will appear from the ensuing description, taken with the accompanying drawings; the invention comprises the various embodiments herein disclosed, and the essential novel features are pointed out in the appended claims.

6n the drawings the same numerals identify the same parts throughout.

Refer ing first to Figs. 1, 2, 3 and 4, I show a pipe comprising a bowl 1 with a detachable stem 2. The bowl 1 has a chamber or cavity 3 for the tobacco and an opening 4 in the bottom. The bowl also has a transverse passage or bore 5 adjacent the bottom communicating with both the opening 4. and chamber 3; and the end of the stem 2 fits into this bore when the bowl is mounted ,on the stem 2. To make the bowl 1 and stem 2 fit together firmly but yieldably, a longitudinal cut or slit 6 is made in the end of the stem 2. Hence the stem can be made with its outside diameter at least as large as the inside diameter of the hole 5; and upon the end of the stern being forced into the opening 5, the portions separated by the cut 6 will be forced toward each other but will be sufficiently resilient to press outwardly against the inside walls or surfaces of this passage and bring about a tight fit between the bowl and stem. On the lower side of the stem, I form a bevelled projection '7, one end of which terminates in an abrupt shoulder 8 to engage the edge of the opening 4 and thus prevent withdrawal of the stem; but when pressure is exerted against this bevelled projection to force up the part of the stem at one side of the cut 6 far enough to enable the shoulder 8 to clear the opening 4, the projection permits the stem to be withdrawn. The stem also has on its outside a shoulder 9 opposing the shoulder 8 to engage the exterior of the bowl adjacent the bottom and prevent the stem from being forced too far into the bowl. On the top side of the stem at the inner end there may be a recess 10 which forms the bottom of the chamber 3 when the stem is in place; and the stem has a longitudinal air flue or passage 11 extending from the outer end of the stem through the entire length thereof, and communicating with the recess 10.

With this form of pipe, the stem can be slipped into place merely by putting one end into the opening of the passage 5 and pushing the stern till the bevelled latch projection '7 reaches the opening 4 and spans same with the shoulder 8 engaging the edge of this opening at one point. During insertion, the two parts of the stem on both sides of the cut 6 will yield to sufficient extent for the latch projection '7 to enter the bore 5; and upon reaching the opening a, the end of the stem will expand so that this projection springs outward into the opening 4. The bowl is then securely mounted on the stern so that it cannot be taken off, unless the latch "I is first released from the bottom opening 4. The sides of this projection are curved as shown in Figs. la so that, by the turning of the stem, the edge of the hole 4 bears with increasing pressure as the slope of the curved protuberance or projection 7 increases, and the latching shoulder 8 is pushed inwardly and out of engagement. Then as soon as the shoulder 8 clears the edge of the opening 4 the stem 2 can be pulled out.

In the form shown in Figs. 5 to 8 inclusive, the bore 5 is placed lower down as shown at 5a so that this bore opens on one side through the bottom of the bowl 1. The stem 2' tapers some what over the portion which is to lie within the bore 50. and this portion may be flattened. at its lower side as shown at 12. The cut 6 makes the stem 2' yieldable as before and the bowl 1 may be yieldable to a slight extent, because of the presence of the bore 511 which bisects the bottom thereof. The pipe and the stem thus cooperate and a double clamping effect is thus produced. Whenever the stem 2' is to be removed it is actuated in such a direction that the stem passes along the bore 5a, the end with the cut 6 leading in the course of this movement.

In the form shown in Figs. 9, 10 and 11, the bowl has a bore 5?) which is open at one side through the bottom of the bowl and has straight instead of curved sides 13. A resilient element in the form of a split tubular sleeve 14 is provided to grip the end of the stern and to be seated in the bore or recess 51). This split sleeve has an aperture 16 in the top which communicates with the chamber 3 in the bowl and along the bottom it has separated edges 15 formed to provide a large central space 16a. At the sides of the element 1% are projections 18 to enter recesses in the sides of the bore 512. This element can be put in place separately forcing it into the bore 51) until the projections 18 register with the recesses and then the sides of the sleeve spring apart so that the sleeve remains in place. The fit between the element 14 and the sides 13 of the bore 5b will not be snug so that when the end of the stem 2, which is cylindrical, is inserted, the sides of the elements 14 can yield a bit and grip the stem 2 firmly. For this purpose the outside diameter of the end of the stem 2 can be slightly larger than the inside diameter of the sleeve 14: when the latter is in place in the bowl, and the stem 2 need not have a split end. The element is will then clamp the stem and hold it as firmly as necessary.

In Figs. 12 to 16 inclusive the bowl 1 is made with a bore 50 which is like that shown at 5b, but does not pass through the bowl 1 from side to side. The connecting element for the bowl and stem has the form of a split cylindrical sleeve led with separated edges 15 shaped to provide an enlarged central place 16a in its bottom and with a boss 18 projecting from the upper side thereof. This element is inserted into the bore or recess 50 and the boss 18 projects into the bot tom of chamber 3 and is afterwards expanded as shown at 18a, to keep it from being pulled out. The cylindrical end of the stem is forced into this clamping sleeve 14a and is firmly but yieldably held thereby as before. The stem at its inner end has a recess 10a which registers with the boss 18.

Figs. 17, i8 and 19 show a pipe with an elongated opening ia in the bottom and with the stem 2 counterbored to provide an enlarged passage in line with the air fiue 11 to receive a short length of tubing 19 split longitudinally over a part of its length as shown at 20. The bowl 1 has a neck 21 through which leads a bore into which tubing 19 can be inserted. The bore in question stops short of the other side of the bowl so that the tubing 19 extends across the opening 4a and the slit 20 establishes communication between the air passage 11 in the stem and the chamber 3. The end of the stem 2 is bevelled as shown at 22 to fit within the corresponding shaped end of the neck 21. The piece of tubing 19 will be attached to the stem 2 and it will have a tight fit with the bowl 1, being compressed when it is forced into the bowl and expanding a little when it is pulled out. This construction also facilitates the easy connection of the bowl and stem and the ready separation of these two parts.

In this last modification the attachable relation of the bowl and stem and the relatively large extent of the bottom hole 4a have a decided cooling effect by reason of the exposure of the lower side of the sleeve 19 through the bottom of the bowl to the air. This efiect is also obtained in some degree by the other forms of my improved pipe in all of which the lower sides of the terminal portions of the stems adjacent the bowls are similarly exposed.

In my invention as above described the separable bowl and stem facilitate cleaning the pipe and the resilient engagement of the bowl and stem seals the bottom of the tobacco chamber and the upper side of the end of the stem within said chamber. This resilient engagement is further necessary to make the bowl shankless and to make the openings at the bottom relatively large in area.

A pipe construction as above described is very strong because in all the forms shown the joint between the stem and bowl is quite durable. If desired the hole 4a in the pipe of Fig. 17 may be omitted, and the split sleeve 19 may terminate in neck 21, which may then be longer.

From the foregoing construction it will be seen that the objects of my invention are fully obtained and while I have have shown certain specific embodiments thereof, I do not wish to be limited to the exact details set forth, but reserve the right to make changes which do not depart from the essential principle of the invention.
